I think this data strongly suggests a mild nerf to Cup and Raven—to something like 10% spell learning efficiency instead of 20 and +6 spd instead of +10. Candle has already been nerfed [somewhat] recently, but still remains a strong all-rounder; these two should be no different, they're way too good as they currently are.
Also, Hurthling Fighter so unfavorable for the first win? People were suggesting Mist Elf Thieves before, I wonder which is worse really (outside of elves dying to random corridor traps in early game 90% of the time).
